ASTM D8-21

Standard Terminology Relating to Materials for Roads and Pavements

SCOPE
1.1 This standard incorporates generic terms and generic definitions of terms specifically associated with road and paving materials. These generic terms and definitions are used within the standards developed by Committee D04 on Road and Paving Materials.  
1.2 Only terms that appear in more than one standard under the jurisdiction of Committee D04 will be included in Section 3 of Terminology D8. Terms that were historically part of this terminology but never appeared, or no longer appear, in more than one standard under the jurisdiction of Committee D04 are listed in Appendix X1. The terms in Appendix X1 are not maintained and updated by Subcommittee D04.91. The terms in Appendix X1 are available for reference purposes only. The terminology in Appendix X1 may not reflect current practices, standards, and technology used in materials for roads and pavements.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
